10 great green houses

Designed by Roland Gundersen at Whole Trees Architecture and Construction, a green design and natural building company. Located in western Wisconsin, this company incorporates carefully chosen, debarked trees into its structures. Each tree is chosen only when it will benefit both the building's structural integrity and when its removal will benefit the forest in which it grows. The Chrysalis Farm House is a passive solar guest house made of whole-tree columns and beams, along with walls made from recycled shipping palettes.
